technical field

The invention relates to the technical equipment field related to electric power engineering, in particular, it relates to a portable cutting device and method for cable sheath.

Background technique

Cable is one of the common connecting cables in power engineering.

In the process of connecting cables to devices such as transformers and switchgears, it is necessary to strip the cable sheaths and then carry out follow-up work. However, the current common stripping method is still to hold the cable with one hand and the cutter with the other, so that the blade penetrates the cable skin and then moves the cutter axially to complete the peeling work.

Because the cable sheath is harder and thicker, in the process of peeling, the situation that the hand or other parts of the body of the cutter often occurs, causing injury to the staff.

Based on the above situation, it is necessary to design a new cable stripper to solve the above problems.

Contents of the invention

The object of the present invention is to provide a portable cutting device for cable sheaths in order to overcome the deficiencies of the above-mentioned prior art. By designing a brand-new structure, the invention can cut the cable sheath conveniently and quickly, and is suitable for cables with different outer diameters.

In order to achieve the above object, the present invention adopts the following technical solutions:

A portable cutting device for cable sheathing comprising:

base;

A sliding cutting mechanism is installed on the left side of the base, and a clamping mechanism is installed on the right side of the base;

There is a clamping groove in the middle of the base;

The clamping mechanism includes an arc-shaped splint located in the clamping groove, the middle part of the arc-shaped splint is fixedly connected to the left end of the screw rod, and both sides are fixedly connected to the longitudinal guide rod;

The base has a through hole matching the screw and the longitudinal guide rod, the right end of the screw rod and the longitudinal guide rod are located in the through hole, the right end of the screw rod and the sleeve form a threaded pair, and the sleeve is driven by the motor. The motor is installed outside the base;

Wherein, the sleeve drives the arc splint to move through the thread pair to complete the clamping of the cable.

Preferably, the sliding cutting mechanism includes a horizontal sliding bar on the base;

The horizontal slide bar is fixedly connected with the positioning rod through the L-shaped rod, and the positioning rod is connected with the thread pair of the handle of a knife, and a cutting knife is fixedly connected with the bottom of the handle of a knife.

Preferably, the positioning rod is arranged vertically.

Preferably, the clamping groove has an arc surface adapted to the arc splint.

While providing the above-mentioned structural solution, the present invention also provides a method for cable stripping using the above-mentioned device, the steps are as follows:

A. Place the cable to be stripped in the clamping groove;

B. Move the curved splint to clamp the cable;

C. Use the cutter to penetrate the cable sheath and insert the pin for positioning;

D. Push the horizontal slide bar to move to complete the cable sheath cutting.

The beneficial effects of the present invention are:

(1) The clamping and cutting of cables with different outer diameters can be realized through the cooperation of the curved splint and the curved surface.

(2) You only need to push the slide bar when cutting, and your hands do not participate in clamping or cutting, which greatly reduces the risk of being injured.

(3) The overall structure is simple, easy to disassemble, and can be placed in a tool box.

detailed description

The present invention will be described in detail below in conjunction with the accompanying drawings.

Embodiment: A portable cutting device for cable sheathing, comprising:

base1;

A sliding cutting mechanism is installed on the left side of the base 1, and a clamping mechanism is installed on the right side of the base 1;

There is a clamping groove in the middle of the base 1;

The clamping mechanism includes an arc-shaped splint 5 located in the clamping groove, the middle part of the arc-shaped splint 5 is fixedly connected to the left end of the screw rod 8, and the two ends of the arc-shaped splint 5 are fixedly connected to the left end of the longitudinal guide rod 9;

The base 1 has a through hole 6 that is compatible with the screw rod 8 and the longitudinal guide rod 9, and the right end of the screw rod 8 and the longitudinal guide rod 9 is located in the through hole 6, and there are 3 through holes 6 in total. The through holes 6 on both sides form a clearance fit with the longitudinal guide rod 9, and a bearing 15 is installed inside the through hole 6 in the middle. The inner ring of the bearing 15 forms an interference fit with the sleeve 14, and the sleeve 14 forms a threaded fit with the screw rod 8. The sleeve 14 is driven directly by the motor 7 .
